        Represents the analytic IDs for Collision Detection Analytics.  
        Possible values are:
        - TARGET_WITH_OTHER_UES: Indicates that the requested analytics is collision
          detection between the sets of target and other VAL UEs within a location.
        - ANY_UES_IN_LOC: Indicates that the requested analytics is collision detection
          between any VAL UEs within given location.
